Primatine Mist = False Positive?

I just realized, I use a Primatine inhaler every morning, and some mornings (like today) 3-4 puffs if I still can't breathe. I searched the Internet for information on Primatine resulting in a false positive, but all I could find were "pass your test" sites that showed Primatine tablets as a false positive for meth, but nothing reliable.

Does anyone know?

There are no more false positives in this day and age. Immunoassay is quite accurate as it is and GC/MS is unique to each chemical. I believe the websites that promote the possiblity of false positives do this to try to sell their products in most cases. The other ones just don't stay up to date.

Thanks FBR! My "common sense" gene kicked in today and I thought, yeah, surely more reputable folks would be talking about it if so.
